Is there a tool?

Recommended Posts

For removing the oscillating weight from a Seiko 7S26 etc. watch movement. I can always use a screwdriver but the slot is actually quite long and it has the bearing race in the middle. Something with a split point I would assume. If one exists, can you point me in the correct direction? My primary goal is to not bugger up the screw slot. You have no idea what I'm really capable of in that area!

The bearing is non removable. A new counterweight has to be used if the bearings are damaged for any reason. Part of this, in fact a large part of this, is me being totally **BLEEP** about not abiding a buggered up screw head. It sends me into a low earth orbit and just shrieks of malpractice IMHO. I learned gunsmithing, up to a point, many years ago and my mentor was a stickler for never sending a piece back out with a damaged screw head in any area that he had worked on. To me, the only worse offense is to find a hair wrapped around a pivot when opening a used watch.

If such a tool exists, I can't find it and I've really looked. I did find a Wiha 4mm x 70mm total length miniature screwdriver. I believe that I can use this to make a proper tool. I will dress the tip to fit into the slot exactly, then use a round file to remove enough metal from the center of the blade to provide proper relief for the bearing race. Other than that, I'm fresh out of ideas.

It shouldn't need much pressure at all to fit it.
If its not going down there must be a reason why.
Has the tube on the hand been damaged or crimped from when you removed it?
Can you fit it with the minute hand removed?

Hi All
I'm a beginner. I've finally competed my Seiko 6119A in a Seiko 5. I now notice that the second hand tube is quite long. It's not sliding down the shaft with moderate pressure. How had should I push? Is there a trick to this?
Thank you

Hello guys,
I have some problem with my seiko 7015 speedtimer that i bought 2 days ago..
This seiko runs smoothly when chronograph off
And when the chronograph is active,the watch runs for awhile and then stop..
Whats wrong with it and maybe you guys can help me with some solution please!!
thanks

Hi Len
thank you for the detailed reply. I tried a 329 today and unfortunately did not work. As you explained before it looks like the rotor is ocillating back and forth (the second hand moves forward and backwards).
Its heartbreaking to see as i was hoping to fix it and give back to my grandfather.
is there anyway i can source the part or an alternative movement (does not have to be Omega) that will fit the dial and casing?Although not ideal as takes away from the integrity and beauty of the watch but would love to able to get it working one way or the other so my grandfather can wear it on the wrist again.
any help would be much appreciated
regards
